Lasas

At first glance, this might appear to be an angel, but it is not! This is a Lasas (or Lasae), an Etruscan grave goddess. According to mythology, everyone has a Lasas that watches over them throughout life (like a sort of guardian angel) and continues watching over them in death by guarding their grave. They are described as fair maidens with wings and wreaths who carry with them a mirror (for that, I do not know the reason).
